Abstract
The Visible Infrared Imager Radiometer Suite (VIIRS) aboard Suomi National Polar-orbiting Partnership satellite (launched in October 2011) has a ground swath of 3000 km and nearly uniform footprint (< ~1 km) size across the full scan. This unique capability enables VIIRS to provide at least once per day observation for any places on Earth at the visible spectrum. Here we present a technique of combining VIIRS's reflectance data the deep blue channels (0.41 and 0.45 μm) with the 3D aerosol distributions simulated from a meso-scale model (WRFChem) to estimate the surface PM at ~1km resolution. The estimates of aerosol optical depth and surface PM are evaluated by comparing them with the ground-based observed counterparts. It is shown that an integrated use of VIIRS reflectance to constrain the WRFChem modeled surface PM give the best agreement with surface observations than WRFChem model or VIIRS standard aerosol product alone.
